Mocking board for APPLE IIc is working

Dear all,

I made PCB and set on my APPLE IIc.

But, there are some debugging points and now It is working now.

I put two small speaker inside of APPLE IIc. looks good.

I'm trying to control the Sound volume as followed APPLE IIc one. but, it's harder than I expected.

I failed to make good control so, I'm not sure can put this function on the board.

Thanks

Ian Kim
